Everything about HVLP Paint Sprayers

Choosing the Right HVLP Paint Spray Gun

When starting out in spray application, choosing the right paint sprayer gun can be difficult. It’s easy to sift through the initial choices, but finding the right types of spray guns can be a little harder. In this guide, users can learn what to consider when selecting a paint spray gun for hobby or commercial use.

HVLP Paint Sprayer

Fluid Viscosity and Atomization Rates Vs Cost

For high-viscosity coatings such as ceramics, enamels and glues, most users choose a regular spray gun. You should consider an airless paint sprayer for spraying heavier coatings during a high production run.

With other types of coatings, paint gun selection depends on the user’s finish requirements. What is your goal? What look at you looking to create? Some thoughts on choices, an hvlp spray gun can reduce the coating with a high transfer efficiency, but a conventional spray gun can provide a higher atomization rate.

Atomization or atomizing is the making of an aerosol, which is a paint particle suspension of tiny/. fine solid particles or liquid droplets in a gas. Basically sending the paint as a particle air charged suspension to your surface as a fine tightly controlled paint spray. The spray gun does yeoman’s work to make your job much easier.

Costs of using spray guns does affect which gun you will choose. A great example is that a conventional paint gun can use twice the paint of an HVLP model.While performance is rated high by some, the cost may be rated even higher by others. Some thoughts on this choice to be contemplated.

Users can get sprayer recommendations from coating technical data sheets. Generally, certain spray guns are better for high-viscosity coatings than others are. You will need to do your homework on this.

Production Requirements

High-quality sprayers are available in a variety of setups. With larger fluid nozzles and air caps, users can choose spray guns that provide the required level of production.

Airless sprayers are an ideal choice when production needs exceed a spray gun’s capabilities. The air cap the user chooses will determine a few things, including spray pattern size and the cap’s ability to break up high-viscosity coatings.

Air Caps Discussion

In talking about air caps there are three types. The HVLP air cap, the HVMP air cap and the conventional air cap. These three differences will translate into two difference maker measurements.

How you measure the transfer efficiency when applying the paint and the quality of the finish you will be able to obtain.

The productivity effectiveness (transfer efficiency) rating goes from the highest rated for effectiveness to lowest. the terms of transfer efficiency you have HVLP, LVMP, and last Conventional Air Caps in descending order.

Finish quality is the in terms of the finish quality in descending order: you have Conventional Air Caps, LVMP, and then HVLP . You will find the difference in finish quality to be very slight from one to another.

A word of warning belongs here in take notice that in some communities the HVMP guns do not meet Federal emissions ratings required by the Federal Government. So be aware of this.

When the user knows their production requirements, they can choose the right air cap and fluid nozzle.

Differences in Feed Types

Feed type is important as well. There are two feed types, gravity feed and suction feed. Gravity feeds are used mainly by people who work with metal equipment like cars and trucks. This type has a top loaded paint cup where gravity feeds the paint down through the spraying mechanism. Since the delivery passage is short this type of sprayer gun lends itself to an easy clean up and leads to longer life through many uses.

The suction type is where the paint cup has a straw type pickup tube. The air pressure from the gun sucks the paint up through the tube and pushes it out the front of the gun. This is very energy intensive.

A pressure pot can offer a higher coating volume, which is ideal when spraying over a gallon of coating at one time. They can also provide greater pressure control, which makes it easier for users to meet production goals. Fluid transfer and diaphragm pumps can offer a continuous feed, and low-viscosity paints are ideal for use in siphon- and gravity-fed spray guns.

Finish Quality Needs

An important variable for users to consider is their finish requirements. While spray guns provide the best-looking finishes, an HVLP, LVMP or conventional gun can achieve an automotive-quality finish.

With a heavier coating, a turbine paint gun can offer good breakup; an airless can provide a quality finish in higher production runs.

Length, Diversity and Method of Sprayer Use

How long will it take you to do the spray paintings?

Are you painting, or staining?

Are you using paint, stain, or thinned down cleaner to clean an area like removing a deck stain.

Seeking the correct paint spray gun for you jobs, whether it is refurbishing furniture, a deck, a front door area, the spray gun that you use can differ widely in terms of price and quality. A higher quality spray gun typically offers a wider variety of fluid nozzles and air caps, and they’re usually completely rebuild able.

A lower cost paint sprayer can’t be fully rebuilt, it basically doesn’t have any flexibility of what it can do. It’s setup options are fairly limited. When a user’s budget is limited, they should strive to find the most versatile spray gun they can afford. The research time is time well spent. Getting the right tool for the job is most important.

Find the Right Spray Gun for the User’s Needs

Choosing the appropriate paint spray gun can be a difficult decision. By learning more about production, finish quality, coating viscosity and compressed air, the user can more accurately determine which paint spraying equipment is best suited to the job’s requirements.
